Safety
!Please note the information provided in the Operating Manual of the PCE.
Read these notes carefully and follow the instructions when you open your
PCE.
– The power switch does not disconnect the device from the line voltage. To do
this, you must pull out the power plug.
– Before opening the unit, first switch it off and then disconnect the power plug.
– No data transmission cable should be connected or disconnected during a
thunderstorm.
– Only qualified technicians may repair the device. Unauthorized opening or
incorrect repair may greatly endanger the user (electric shock, fire risk).
– Correct operation of the PC in accordance with IEC 950/EN60950 (cooling,
protection against fire, RFI suppression) is guaranteed only if the housing is
closed. Also put back the back cover for the slots.
– Install only system expansions that satisfy the requirements and rules governing
safety and electromagnetic compatibility and relating to telecommunications
terminal equipment. If you install other expansions, you may damage the
system or violate the safety regulations and regulations governing RFI
suppression. Information on which system expansions are suitable can be
obtained from the customer service or your sales office.
– The power supply unit (marked with a lightening flash symbol) should be
removed and replaced only by authorized specialists.
– If your PCE is equipped with a power outage fallback facility, the battery block
should be removed and replaced only by authorized specialists.
